Abstract: A magnetic head positioning device for multi-track tape recorders consisting essentially of a pivotally mounted head carrier which pivots in a plane at right angles to the plane of the tape. In every position of the head carrier, the head is substantially at right angles to the surface of the tape to be scanned, and the distance between the head and the pivotal axis of the carrier is many times greater than the width of the magnetic tape. In one embodiment, the head carrier is in the form of a lever having an offset portion and is pivotally mounted opposite the capstan. In another embodiment a straight lever is provided which is pivotally mounted on the capstan side of the recorder. In a further embodiment of the invention, the end of the lever which carries the magnetic head can be pivoted in a slot in a tape guide in a plane substantially at right angles to the guide surface. The device is used preferentially for transports for very flexible tapes and extremely high track densities.

Abstract: A process for resolving racemic alpha -hydroxy- beta , beta -dimethyl- gamma -butyrolactone, referred to as D,L-pantolactone, into its optical antipodes, based on the separation of diastereomeric salts of D,L-pantoic acid ( alpha , gamma -dihydroxy- beta , beta -dimethylbutyric acid), produced from D,L-pantolactone, by means of (-)-3-aminomethylpinane, (+)-3-aminomethylpinane or one of their acid addition salts, as a new resolving agent.

Abstract: A tape guide, especially a guide for thin magnetic tapes which are subjected to strong acceleration forces in the longitudinal direction, and a tape transport apparatus with a central capstan, comprising such a tape guide. The tape guide includes one or two rotatable, but fixedly arranged guide rollers having flanges arranged around part of the periphery thereof, which flanges each have an ingress and an egress chamfer for the tape. When one guide roller is used, the magnetic head is positioned between a tape reel and the guide roller and, when two guide rollers are used, it is positioned between the said two rollers, the magnetic head bearing against the unsupported span of tape in each case. The tape guide may be provided with means for producing cushions of air for stabilizing the roller as it rotates.
